Nvidia Publishes Geforce 310.70 Beta Driver
Nvidia just released a beta version of the GeForce 310.70 Driver, which rolls up previously beta driver updates such as performance improvements for Call of Duty: Black Ops 2 and Assassin's Creed III.
According to Nvidia, the driver will deliver up to 26 percent faster performance in Call of Duty: Black Ops 2, 38 percent speed increase in Far Cry 3, and up to 18 percent faster performance in Assassin’s Creed III, and shimmer-free graphics with TXAA antialiasing in both games.
Nvidia said that the driver will also provide a substantial performance boost in several other games, including Far Cry 3, battlefield 3, StarCraft II and Dragon Age II on GeForce 400/500/600 cards. 12 game titles received SLI profiles, 37 titles got 3D profiles.
Noteworthy is also the addition of CUDA5 support, PhysX version 9.12.1031, as well as OpenGL 4.3 support for GeForce 400-series and later GPUs.

I'd understand if it was a major release with substantial improvements and new features.. but this?
Last year, Tom's hardware did a driver comparison of a 5850 (I think). They compared drivers from launch to the latest one, and noticed that the 5850's performance increased to a 5870's level from just updating from the launch drivers to the latest ones.
It is news. Go and read the notes, some significant perf. updates. My GW2 now runs smoother.
I remembered also that the week after that article, they did the same thing with the GTX 480. I would like Toms to do another one of these performance reports on how drivers have improved two-three years after the release of the Fermi architecture.

Now, if only Tom's could be more up to date with their news...
I already had the latest drivers (306.97) and they worked fine. There is no reason for me to switch drivers.
These performance improvements were made available in the previous couple of betas, this is merely a bug fix release.
Get Nvidia System Tools. Install the performance tool (aka NTune) and you can OC from the control panel, if you don't want to use MSI afterburner or RivaTuner.
I did use MSI Afterburner to OC my card. Will give Nvidia System Tools a try.
Thank you!
